How to select centrifugal compressor? Key considerations of type selection decision

As a key power equipment in such industrial production fields as air separation, iron and steel, biological fermentation, electronics and petrochemicals, the correct selection of equipment in engineering practice is the prerequisite for ensuring highly energy-efficient and stable system operation. So how do you select a centrifugal compressor? We must not only integrate operating parameters and match the drive method, but also choose a reliable centrifugal compressor manufacturer, with key scrutiny on its response speed of localized technical service, its spare parts inventory, its commissioning expertise, and the completeness of its regular maintenance service. A manufacturer with a well-established service network can provide fast and effective technical support when equipment fails, thereby minimizing production losses to the greatest extent. Below, Turbo-Tech introduces in detail the selection approach and steps for centrifugal compressors.
I.How to select centrifugal compressor? Key considerations of type selection decision
Clarify the operating parameters
The first step in selection is to accurately grasp the operating conditions, which mainly include the following core parameters:
Discharge volume (flow rate): determine the actual gas volume required by the process, usually expressed in Nm³/min or m³/h, and allow a certain margin — generally a 5%–10% increase over the theoretical flow rate is recommended.
Discharge pressure: determine the discharge gauge pressure according to the requirements of the downstream process; this is the key indicator that determines the number of compression stages and the structural design.
Inlet conditions: including inlet pressure, inlet temperature and medium composition. Altitude directly affects the intake volume, so corresponding parameter corrections are required in high-altitude areas.
Properties of the medium: the type of gas being compressed, its density, molecular weight, and whether it contains corrosive components all affect the selection of machine materials and sealing form.
Determine the compressor type and structure
Based on the flow rate and pressure parameters, determine the basic structure of the compressor:
Single-stage high-speed centrifugal compressor: suitable for medium- and low-pressure applications, with a compact structure and high efficiency.
Multistage centrifugal compressor: suitable for large-flow, high-pressure process flows, achieving high discharge pressure through multistage arrangement in series.
Verify qualifications and certifications
Give priority to products that have obtained authoritative certifications such as TÜV Class 0 oil-free certification and Grade 1 energy efficiency;
verify whether the manufacturer holds qualifications such as a “Specialized, Refined, Differentiated and Innovative (SRDI)” enterprise or a High-Tech Enterprise;
pay attention to participation in industry standards (for example, Turbo-Tech has participated in the formulation of a number of industry standards);
verify whether there are implementation cases in the same industry and third-party measured data.
Evaluate the total cost of ownership
Initial purchase cost: compare quotations for products of the same specification;
Maintenance cost: service life of core components, maintenance intervals, price of spare parts;
Service response: coverage of service outlets, spare parts inventory rate, and 7×24-hour response capability.
